【摘要】：本文圍繞著電荷轉(zhuǎn)移鹽雜化納米材料的制備為主題,一方面以無機(jī)半導(dǎo)體材料和有機(jī)電荷轉(zhuǎn)移鹽為基本的構(gòu)筑單元,利用模板法,合成了具有雜化界面的一維有機(jī)/無機(jī)異質(zhì)結(jié)納米線,并且通過實(shí)驗(yàn)條件的改變,可控的調(diào)節(jié)了異質(zhì)結(jié)納米線的形貌結(jié)構(gòu)以及它的電學(xué)性質(zhì);另一方面,以碳的新型同素異形體和有機(jī)電荷轉(zhuǎn)移鹽為基本的構(gòu)筑單元,利用氣相沉積法,合成了有機(jī)/有機(jī)雜化納米材料,并對其場發(fā)射性質(zhì)進(jìn)行了研究。主要包括以下幾個(gè)方面:(1)利用模板法,制備出了Cu TCNQ/Cu S(TCNQ為7,7,8,8-四菁基對二苯甲烷)異質(zhì)結(jié)納米線,并且分別對大面積的異質(zhì)結(jié)納米線陣列和單根的異質(zhì)結(jié)納米線進(jìn)行了形貌、電學(xué)性質(zhì)的表征。研究表明,所制備出來的異質(zhì)結(jié)納米線擁有高的整流比,其中異質(zhì)結(jié)納米陣列的整流比會隨著光照強(qiáng)度的增強(qiáng)而增大。這使得Cu TCNQ/Cu S異質(zhì)結(jié)納米線可能會成為新一代的光電器件。(2)通過改變實(shí)驗(yàn)的條件,制備出了四種不同結(jié)面積的Cu TCNQ/Cu S異質(zhì)結(jié)納米線,并且對其電學(xué)性質(zhì)和形貌之間的關(guān)系進(jìn)行了探究。研究表明,Cu TCNQ/Cu S異質(zhì)結(jié)納米線的二極管整流比會隨著異質(zhì)結(jié)結(jié)面積的增大而減小。這為我們想要獲得高整流比的二極管材料提供了新的思路。(3)利用溶液聚合的方法在銅片上成功的制備了大面積的石墨炔薄膜,并對其形貌進(jìn)行了表征。利用氣相沉積法在石墨炔薄膜上長出Cu TCNQ納米線,成功的制備出了石墨炔/Cu TCNQ雜化納米材料,并對它的形貌以及場發(fā)射性能做了研究。研究表明,石墨炔/Cu TCNQ雜化納米材料具有優(yōu)良的場發(fā)射性質(zhì)。通過對其功能函數(shù)進(jìn)行了計(jì)算,結(jié)果表明其具有較低的功能函數(shù),同時(shí)場發(fā)射穩(wěn)定性試驗(yàn)表明石墨炔/Cu TCNQ雜化納米材料的場發(fā)射穩(wěn)定性很高。
[Abstract]:This paper focuses on the preparation of charge transfer salt hybrid nanomaterials. On the one hand, using inorganic semiconductor materials and organic charge transfer salts as the basic building units, the template method is used. One-dimensional organic / inorganic heterojunction nanowires with hybrid interface were synthesized. The morphology and structure of heterojunction nanowires and their electrical properties were controlled by changing the experimental conditions. Organic / organic hybrid nanomaterials were synthesized by Vapor deposition using new carbon isoforms and organic charge transfer salts as basic building units. The field emission properties of Cu TCNQ/Cu TCNQ were studied, including the following aspects: 1) using template method, Cu TCNQ/Cu TCNQ was prepared, which was 7? 7? 8? 8? Tetracyanine) heterojunction nanowires. The morphology and electrical properties of large area heterojunction nanowire arrays and single heterojunction nanowires were characterized respectively. The results show that the prepared heterojunction nanowires have a high rectifying ratio. The rectifying ratio of heterojunction nanoarrays increases with the increase of light intensity, which makes Cu TCNQ/Cu S heterojunction nanowires become a new generation of optoelectronic devices by changing the experimental conditions. Four kinds of Cu TCNQ/Cu S heterojunction nanowires with different junction areas were prepared. The relationship between electrical properties and morphology is also investigated. The results show that the diode rectifier ratio of Cu TCNQ/Cu S heterojunction nanowires decreases with the increase of heterojunction area, which is why we want to obtain high rectifier ratio. (3) large area graphite thin films were successfully prepared on copper substrates by solution polymerization. The Cu TCNQ nanowires were grown on graphene thin films by vapor deposition, and the graphene / Cu TCNQ hybrid nanomaterials were successfully prepared. The morphology and field emission properties of Cu / TCNQ hybrid nanomaterials were studied. Graphene / Cu TCNQ hybrid nanomaterials have excellent field emission properties. At the same time, the field emission stability of graphene / Cu TCNQ hybrid nanomaterials is very high.
